FLOOR.

Specification of Letters Patent.

Patented July 16, 1918.

Original application filed July 28, 1916, Serial No. 111,928. Dividedand this application filed September 18, 1917. Serial No. 191,990.

To all whom it may concern:

Be it known that I, NORMAN JOHN MAC- DONALD, of the city of .Winnipeg,in the Province of Manitoba, Canada, have invented certain new anduseful Improvements in Floors, of which the following is thespecification.

The invention relates to improvements in fioorsand the object of theinvention, which is a division from application Number 111,928, filedJuly 28, 1916, is to provide an inexpensive easily constructed floorwhich can be quickly set up. whenrequired for use and as easily takendown for shipping or storage purposes and while providing a floor ofthis type, construct it so that it will be tight fitting, whichfeatureis an important one as will readily be appreciated.

A still further object of the invention is to constructafloor whichrequires no nailin or similar permanent fastenings when being set up,and while avoiding these, to supply a rigid structure serviceable as aflooring. V v c I I.

With the above objects in-view the invention consists essentially in asubstantially rectangular take-down frame, a floor formed fromfloorboards insertible within the frame, filling strips associated withthe floor boards and floor joists or sleepers passing lengthwise of theframe and beneath the floor boardsthe parts being arranged andconstructed as hereinafter more particularly described and later pointedout in the appended claims, reference being had to the accompanyingdrawing in which Figure 1 represents a perspective view of a floorconstructed in accordance with my invention, parts of-the floor beingbroken away to expose construction. m

Fig. 2 represents an enlarged detailed perspective View of one of thecorner joints of t e frame, the said joint being pulled apart.

Fig. 3 represents a vertical sectional view through the floor at theend. I

I have found hat there is considerable demand for a collapsibleior'knockdown floor which can be utilized for camping purposesseasonafter season or as" the floor of a sectional house and invordertdsupply-such a demand I have invented the present floor which canbe manufactured cheaply, can be set up or taken down quickly and is ofsu he naturezthat'it-canbe shippe r t red very conveniently. v Refe eessew m the stems i Wi h like characters of reference indicatecorresponding parts in the several figures.

1 represents a substantially rectangular floor frame formed from similarside members 2 and 8 and similar end members 4 and 5. The said side andend members are actually made from a body or main strip 6, to the topand bottom sides of which I permanently, fasten, suchas by nailing,equal width top and bottom strips 7 and 8, the outer edges of the latterstrips lying flush with the outer edge of the main strip while the inneredges of the top and bottom strips overhang the inner edge of the bodystrips and form with it a channel 9.

It will here be observed that the main strips of the end members 4: and5 are somewhat longer than the attached top and bottom strips so thatthey project in extensions 6 and 6 which are adapted to be receivedbetween the extending ends 7 and 8 of the top and bottom strips of theside members of the frame.

From the above construction it will be obvious that the frame memberscan be quickly put together by fitting the extending ends 6 and 6 of theend members between the extensions 7 and 8 of the side members andholding them together by inserting through the openings 10, corner bolts11.

In this connection it is to be noticed that once the corner bolts areinserted the frame is more or less a rigid one as the manner in whichthe corners go together provides a tight fittingcorner once the bolt isinserted.

The end members of the frame are arranged to lie on floor joists orsleepers 12, which joists have their ends rabbeted away as indicated at12 to receive the lower cross strips of the end'members 4: and 5 in sucha manner that their upper faces Will lie flush with the upper faces ofthe said cross strips. The joists are held to the end members byinserting bolts 13 through the joists and the end members,registering-openings being provided. j

Within the frame I insert floor boards 14 which floor boards passinadirection at right angles to the joists on which they lie. The floorboards are all of an equal length and are-so, adapted that when inposition their. ends lie in the" channels of the side members 2 and 3.In connection with the insertion of these floor boards within the I maymention that I have found it fr m he h h a sale 019 de r le to e ter bycutting away a portion of the body strip 3 6. By providing this openingit will be seen that I am-able toset the frame noon the joists and thenput the floor boards in porsition -by threading them, so to speak,

through the opening 15 until the cn'dsthereof take theirpositions in thechannels and then sliding the boards one after the other inoppositedirections to the ends of the frame.

In the drawing I have shown the last board to beinserted as onlypartially in and I- have also-shown the inner or advanced end of thisboard- With its sides slightly cutaway to provide a more or less Wedgeshaped or driving end- 14*. This arrangement allows ofthe easy enteringof the last floor board to be laid and, also permits of the effectivetightening up of the floor, as after the pointed end of the lastfioorboard has beeirinserted through the opening" it can be driven in by} amallet to close the cracks in the floor.

After the floor boards have been placed in positionfilling strips '16are-inserted Within "thechannels'abovethe floor boards and beilyapparent that this floor can be ;very

quickly set up and as easily taken apart and that it requires nospecialtools to lay it and further that it is a particularlyneatflight,convenient, and durable floor for camping or other similar purposes.

VV hi1e lhaveideseribed one, and possibly the most preferable, mannerofsettingflup the floorstill it 'will be understoodthat this is not theonly Way it can be set up in a *quick and eflicient manner as'obviously'the i --frame could be set up. With one of the side '-membersremoved and the-floor boards could be placed in position on the attachedjoists and 'then'the removed side piece could be 'fiirallyplaced inposition onthe ends of the boards.
